- TLS Version(s):
- TLS1.2
- Protocol:
- Transport Layer Security (TLS)
- Key Exchange:

- Authentication
- Rivest Shamir Adleman algorithm (RSA)
- Encryption:
- ARIA with 256bit key in Galois/Counter mode (ARIA 256 GCM)

Non-ephemeral Diffie-Hellman:
Diffie-Hellman key exchanges not using ephemeral keys do not support Perfect Forward Secrecy (PFS) which is recommended, so attackers cannot decrypt the whole communication stream.
